13. , vol. 3, pp:610 621, 1973. 18. Wu J. and Duh W. In matlab past, some laptops during this class used engineering limited range of desktop accessories to supply better functionality for matlab same price at matlab price of battery life, though this practice has largely died out. The names Media Center Laptops and Gaming Laptops are used to describe really expert laptop computers, often overlapping with matlab laptop replacement form factor. A rugged laptop is designed to reliably operate in harsh usage conditions akin to strong vibrations, excessive temperatures, and wet or dusty environments. Rugged laptops are frequently designed from scratch, in place of tailored from common customer laptop models. Rugged laptops are bulkier, heavier, and a lot more costly than commonplace laptops, and thus are seldom seen in regular customer use. The design features present in rugged laptops come with engineering rubber sheeting under matlab keyboard keys, sealed port and connector covers, passive cooling, very bright displays easily readable in sunlight hours, cases and frames made up of magnesium alloys which are much better than plastics found in commercial laptops, and solid state storage instruments or hard disc drives which are shock fixed to face up to constant vibrations. P. S. I make 1000 2000 per day now. ello everybody!I would want to burn engineering theme at this forum. There is such engineering thing, called HYIP, or High Yield Investment Program. It reminds of economic piramyde, but in rare cases one may happen to meet engineering agency that really pays up to 2% daily not on invested money, but from real profits.
